Title: Top feeding and ejecting materials handling device and method
Inventor: OUELLETTE JOSEPH F
IPC: B65G59/00
Filed: 1979-10-10
Granted: 1983-12-27
Abstract: TOP FEEDING AND EJECTING MATERIALS HANDLING DEVICE AND METHOD Abstract A materials handling device, such as a palletizer and depalletizer, has a mechanism for feeding pallets to be loaded, and ejecting pallets which have been unloaded, at the top of the device. When operated in the unloading mode, a loaded pallet is introduced into an unloading bay and placed on an elevator. The elevator is sequentially indexed upward a distance equal to each layer to be unloaded. The indexing is automatically sequenced after the last article in the layer is unloaded. Sensing devices detect when the last article has been removed. When the final, or bottom, layer on the pallet is reached, sensing devices sense the presence of the pallet and automatically index the pallet upward an additional distance so that it may be engaged by a transversely operating carriage. The elevator in the unloading bay is then moved down to the bottom of the un-loading bay. When the final layer is being unloaded a second pallet is placed in position on the elevator and in-dexed upwardly to a ready position slightly below the pallet which is being unloaded. When the final layer has been un-loaded, the carriage is operated to eject the pallet trans-versely out of the top of the unloading bay. The elevator is then indexed upwardly in just a few seconds to position a new pallet to be unloaded. While the second pallet is being unloaded the ejected pallet is indexed for subsequent stacking on an elevator in the storage bay of the machine. When the transverse carriage reaches the storage bay, in-dexing plows position the pallet on the carriage to a stand-ard position. The carriage remains in the storage bay until the final layer on the unloading pallet is reached and the pallet has been indexed upwardly an additional distance. Then the carriage moves into the unloading bay to support the unloading pallet. The previous pallet in the storage bay is dropped onto the elevator when the carriage leaves the storage bay. The storage bay elevator is positioned a short distance below the position of the transverse carriage. When the pallet is placed on the storage elevator, the elevator is automatically indexed down a distance past a sensor and then indexed back up so that the loaded pallet is spaced a short distance below the position of the next ejected pallet. The device can be operated in the palletizing mode by reversing the above described operation. The storage bay remains the storage bay for supplying empty pallets and the un-loading bay becomes the loading bay.

Abstract: THE PRODUCTION OF A SELECTIVELY PROTECTED N-ACYLATED DERIVATIVE OF AN AMINOGLYCOSIDIC ANTIBIOTIC            ABSTRACT OF THE DISCLOSURE       Aminoglycosidic antibiotic comprising a 6-0-(3"-aminoglycosyl)-2-deoxystreptamine optionally having a 4-0-(aminogycosyl) group, such as kanamycins, gentamicins, sisomicin, forms reversible complex with zinc cations by association of the zinc cations with some pairs of amino-hydroxyl groups in the aminoglycoside, and the zinc-complexed amino groups are blocked from acylation.  Reaction of this zinc complex with an acylation reagent having an amino-blocking acyl group brings about acylation of the non-complexed amino groups to give an N-acylated zinc complex, namely a complex of zinc cation with an N-acylated aminoglycosidic antibiotic derivative.  Removal of zinc cations from N-acylated zinc complex yields a partially N-acylated amino-glycosidic antibiotic where 1- and 3"-amino groups are unprotected but all other amino groups protected with acyl group.  Further reaction of this partially N-acylated product with a certain alkanoic acid or N-formyl-imidazole results in preferential acylation of 3"-amino group without l-amino group being acylated, affording a l-N-unprotected and other N-fully-protected derivative of the aminoglycosidic antibiotic which is valuable to be l-N-acylated with .alpha.-hydroxy-.omega.-amino-alkanoic acid for high-yield production of known semi-synthetic l-N-(.alpha.-hydroxy-.omega.-aminoalkanoyl)-aminoglycosidic antibiotic.

Abstract: ABSTRACT OF THE DISCLOSURE         A thermostat for generating control signals for a furnace, air conditioner, or the like, employs a constant frequency periodic source and an oscillator incorporating element having a thermal-sensitive electrical characteristic so the oscillator frequency varies as a function of the ambient temperature.  A comparator receives the two outputs and gener-ates a signal representative of the ambient temperature.  The stable output is also provided to dividing circuits to generate a signal representative of the time that is used to interrogate a digital memory storing a desired temperature-time program for the thermostat for a repetitive period, such as a week or month.          The ambient temperature signal is compared with the desired temperature signal to generate an output control signal.  A display provides a read-out of time and temperature and is used along with a keyboard or the like in programming the memory.

Abstract: ABSTRACT    There is disclosed a dust seal for a tool device, including a bit receiving end, which comprises typically, an elastomeric material such as neoprene and includes a first end portion having a first axially extending opening of predetermined dimension and having a shape and contour which complements and cooperates with the aligned surface of the tool bit.  The predetermined dimension is selected so as to create a first interference fit with the tool bit.  The seal includes a second end portion axially dis-posed from the first and connected thereto.  The latter includes a second axially extending opening, again of predetermined dimen-sion which has a shape and contour which complements and co-operates with the aligned surface of the bit receiving end.  The dimension of this second opening is selected to as to provide a second interference fit with the aligned surface of the bit receiving end, the second interference fit being lighter than the interference fit formed between the first end portion of the seal and the bit shank.  The difference in interference fits allows for the seal to move substantially in unison with the bit while slipping upon the contacted surface of the bit receiving end.          Cooperative action between a surface of the second end portion and a flange on the bit receiving end ensures retention of the seal upon the tool device when the bit is removed from the tool.
